the 4 port one above is very tiny, hardly a giant hub.
i suppose that there is a group of people that don't own more then 4 usb devices (which makes using a hub mandatory) yet are also willing to pay $15 per port to save reaching around.
in my mind the price premium doesn't justify the issue addressed, the 10 port one is underneath my iMac screen, on the pedestal, so it takes up zero usable space and is quite attractive, the aluminum matches perfectly. I cannot imagine it offending the austere aesthetics of even the most OCD desk jockey. It looks like it is part of the computer.
of course I personally need two 8 port hubs behind my iMac and the 10 port one in the front, so I cannot even really relate to the user who gets by on the 4 supplied ports.
